If the purpose of the tracheotomy is to allow air into the lungs as quickly as possible, the incision should be made in the…

c-shaped cartilage rings

what is the membrane that is adherent to the lung?

Visceral pleura

what is the membrane a few mm away from it?

Parietal pleura

what fills the space between the two membranes?

Pleural fluid

what forms the fluid?

The pleura

pseudo unipolar neuron: both processes have....

myelin

How do we know we're in the peripheral nervous system?

Axons attach to muscle

What forms myelin

Schwann cells (glial cell)

multiple schlerosis is an autoimmune disease the myelin sheath slowly disappears. Myelin in the cns is formed by what?

oligodendrites

Can these fibers myelinate more than one process from a neuron?

Yes

what part of the neural tube does the basal ganglia come from?

Tele-encephalon

the cellular organelle that continuously renews protein in the membranes and cytoplasm of a neuron is called what?

Nissle

How much CSF is formed/day?

700 cc

What is a junction between two schwann cells?

Node of ranvier

What is a junction between two nerve cells?

synapse

astrocyte

glial cell with many functions

what do glial cells do?

Metabolic and structural support cell for the nerve cell

group of neurons outside the CNS

ganglia

Most nerve cells in the CNS are

internuerons

What category are pyramidal cells in the crebral cortex?

interneurons

What is the area between the grey matter and the edge of the spinal cord?

lishour fasiculus
(pain and temp)

From the hemispheres the CSF flows into the ventricles between the thalami and the hypothalami

: the 3rd ventricle

From the 3rd, the CSF flows into a thin ventricle runs from 3rd to midbrain:

aqueduct.

this is just extra

The flow of CSF flows from lateral to intraventricular foramen to 3rd ventricle to aqueduct to 4th. From the 4th, CSF goes outside the brain and into sinuses. CSF forming in the ventricles flows outside the brain in the arachnoid space to get to the sinuses.

cerebral spinal fluid (CSF) in the 3rd ventricle flows into what?

Aquaduct

17. the 3rd neuron in a sensory pathway from the cord is found where?

Thalamus

what sensory nerve supplies the teeth?

5th cranial nerve

if left lateral spino-thalamic tract is damaged at T2, where do we get lack of sensation(pain and temperature)?

Below right T3 and T4

conscious proprioception is coming up what?

posterior funiculus

prefrontal functions

planning, working memory, judgement, sequencing, initiative.

Astero agnosis is the answer

what is the gyrus at the end of the lateral fissure

Supermarginal

fibers originating in motor cortex coming down in what tract?

Cortico-spinal and cortico bulbar

in general where does the cortico-bulbar tract go? Specifically?

Cranial nerve motor nuclei
7th cranial nerve

2 main divisions of prosencephalon

diencephalons and telencephalon.

Rombincephalon separate into which two?

metencephalon and myelencephalon

myelencephalon gives rise to what?

medulla

Which of these do viscreal efferent fibers innervate?

Heart

Axon hillock

where axon attaches to neuron
has no nissl substance
